RADIATOR.

SPECIFICATION forming part of Letters Patent h l'o. 260,512, dated July 4, 18 82.

Application filed March 13,1882. (Nomodeh) full, clear, and exact description of the same,

reference being had to the accompanying drawings, in Which- Figure 1 is a central vertical section of the radiator. Fig.2 is a similar view, with the addition of an exterior casing. Fig. 3 is a plan,

partially in section, of one of the radiatingdrums on an enlarged scale. Fig. 4 is a sectional view of the screw-joint between two of the radiating-drums. Fig. 5 is a sectional view of the radiator as attached to a side wall.

Ourimprovement relates to steam-radiators for heating buildings; and the invention consists in a series of radiatingdrums, constructed each with air-tubes to allow free passage of air through the drum, and a projecting flange at one end extending around the whole perimeter, so that when the drums are placed one upon another a continuous and unbroken exterior surface is presented, while a thin air-space is left between each two of the. drums, whereby the air-currents are broken and dilfused while passing from one drum to the other, as hereinafter more fully described. i

In the drawings, A represents a base for supporting the radiators, which base may be of any ornamental form.

B B are the radiators, which may be of any desired form, but preferably circular and cylindrical, as shown.. Each of these radiators consists of a hollow steam-chamber having a series of open-ended tubes, at a, through which air is allowed to flow freely, being thereby subo jected to the action of the steam-heat which radiates through the casting.

The base A is provided with a pipe-section, b, which connects with the live-steam pipe and supplies the radiators with steam. The first radiator is screwed thereon or connected therewith by a screw-nipple, c, as shown in the enlarged sectional view, Fig. 4. The second radiator is secured on topof the first in the same manner, and so on till the necessary number of radiators has been built up. The screwconnection is in the center, each of the radiators having a hollow hub for the purpose, and by this means the steam passes from one radiator to another clear to the top. The opening at the top of the upper radiator is closed, and is provided with a pet-cock.

At the bottom of each radiator is a circular projecting flange, 01, extending beyond the closed bottom, so that when one radiator is attached to another, as described, a space, f, will be left between the two radiators, said space serving as a distributer to the air. The air passing through the tubes of the lower radiator enters this space f and is spread over its whole surface; thence it enters the tubes of the next radiator, and so on till it escapes at the top. By this means the air is not only heated in passing the tubes at a, but when it reaches the space f it is spread over a large surface in a thin body, and is subjectedto heat from the ends of both radiators, by which the maximum efi'ect is produced. One great advantage is that the air in passing has a circuitous route,

which enables it to extract all the heat. In is putting up any capacity may be attained by simply building higher.

In Fig. 5 the radiator is shown as attached to a side wall, being suspended by hooks g g or otherwise. Any desired number of the drums may be used in this way. In such case the live-steam pipe enters at the top, and an exit-pipe is provided at the bottom for the escape of the waters of condensation. The ra diator is in convenient form, not only for standing upright on a floor, but also for being attached to side walls in rooms, or on cars, vessels, &c.

In Figs. 2 and 5 an exterior casing, J, is shown, leaving a jacket-space between itself and the radiators. The apparatus may be used either with or without this casing. The casing is provided with one or more registers, h, at the end, by which the flow of the heated air may be controlled. By the use of thecasing the heat may be controlled without controlling it by cutting off the steam.

We do not wish to confine ourselves to the particular form of radiators shown, as they may be made of any other form with a similar efl'ect.

In some cases it may be necessary to use extra steam-passages connecting the radiators, and under such circumstances a pipe, L, is employed, connecting the sides of the upper and lower radiators, as shown in Fig. 1.

If desired, the tubes at a may be made square or of other form in cross-section, instead of round, and where the radiators are attached to side walls vertical tubes may also be employed.

Having thus described our invention, we do not claim broadly a radiator made of separate drum-sections.

We claim 1. The radiator-section consisting of the drum 13, made fiat on top, provided with the projecting flange d on its bottom, extending around the whole perimeter, and having the air-tubes a a, whereby when the drums are placed one upon another a continuous exterior surface is produced and air-spaces f are formed between the drums, as shown and described, and for the purpose specified.

2. A steam-radiator consisting of a series of drums placed one upon another and united by 25 screw-joints, said drums bein g constructed with flat tops, projecting flanged bottoms, and with air-tubes extending through the drums, whereby the exterior surface of the radiator is continuous and unbroken from bottom to top, and 0 air spaces are formed between the drums for breaking the continuity of the air-currents as they pass from one drum to another, as set forth.

In testimony whereof we have hereunto 3 5 signed our names in presence of two subscribing witnesses.
